Agreed. I'm uneasy about boats designed after the creation of F16 taking advantage of the grandfather clause, but I think the big concern for the class is that such Open F16 boats should not pass themselves off as true F16 designs. Unlike the other grandfathered boats, the makers of the Evolution appear to be making the F16 "conformance" a selling point.

If we are to build the class, we need people to buy true F16 designs, so buyers need to be clear what they're getting.
